KarmaFX Synth Modular 20 Year Anniversary !

Wed, 23 Apr 2025

April 23, 2025 marks a special milestone - the 20 year anniversary of the first public release of KarmaFX Synth Modular ! While development did start earlier, version 0.85 was the first official release, revealed to the public on April 23, 2005! From day one, KarmaFX Synth was built with a bold ambition: To be a synthesizer that could do it all. It combined subtractive, additive, wavetable, sample-based, and granular synthesis - all under one roof. Packed with powerful filters, effects, and modulation capabilities, it allowed any signal to modulate any knob, staying true to its modular nature.

Over the years, KarmaFX Synth Modular has earned its place in the spotlight:

  • Honorable mention in Future Music Magazine, July 2005.
  • Named Best Soft Synth by Computer Music Magazine, 2007.
  • Featured in the book "Becoming a Synthesizer Wizard" by Simon Cann, 2009.
  • Featured over 40 times in Computer Music Magazine's "Synth Essentials" column.
  • Received top ratings from KVR, Computer Music Magazine, BEAT, and MusicRadar, 2009.
  • Winner of the Technofile Silver Award, 2016.
  • Endorsed by legendary artists such as Bill Halsey (Cosmosis) and Chris Menzi (Wavetraxx).

Today, KarmaFX Synth Modular is more powerful than ever. The newly released version 2.02 is available for PC/Windows and Mac/OS X (Intel & Apple Silicon) in VST2, VST3, and Audio Unit formats. For KarmaFX, this journey has been an honor and a privilege. We're deeply grateful to the users, artists, and supporters who've been part of this evolving sonic adventure. In the future, KarmaFX hopes to continue to push the boundaries of creative sound design. If you want to support this journey, please become a registered user by purchasing your copy of KarmaFX Synth Modular 2 - or show your love by donating to the KarmaFX Plugin Pack. Here's to 20 years of sonic exploration - and the many more to come !

KarmaFX Synth Modular 2.02 Released

Thu, 25 Jul 2024

KarmaFX is thrilled to announce the release of KarmaFX Synth Modular 2.02!

This version introduces VST3 support and Apple Silicon support for Mac/OSX. New audio features include Stereo Modulation, Improved Unison, a new Parametric Allpass Filter, a Boost module that emulates an Analog Boost effect, and a Clock module that outputs a steady and optionally free-running clock-signal synced to DAW tempo. The release also contains important bug fixes, performance tweaks, and new and improved patches.

See the full changelog below.
The update will download automatically for all registered users.
Uninstalling any previous installation before installing the new version is recommended but not required.

Huge thanks and shout-out to the beta-testers and contributors! Special thanks to Jan for assistance with VST3 and Apple Silicon!

KarmaFX Synth Modular 2.02 Build 436 Changelog. [Release 25 Jul 2024]
  • Added VST3 plugins for PC/Windows and Mac/OSX using latest VST3 SDK 3.7.11, including support for MPE and MIDI-Learn.
  • Unison: Reworked and improved Unison module. Added Phase Spread, (frequency) Spread, reworked Stereo spread, and new Mix and Kybd Tracking parameters.
  • Unison: Added Exp(onential)/Lin(ear), Antiphase, AntiPhase LFO, Invert and (Detune) Anti-Phasing options to Unison module.
  • Unison: Split Unison's "Mode" into three parameters: A regular spread-mode, an octave-mode and a chord-mode.
  • Unison: Added "Super" mode to emulate the frequency-spread of Roland's JP8000 SuperSaw.
  • Unison: Added "Monitor" option to show current Unison spread-design in wave-display GUI.
  • Stereo Modulation: Modulation modules that now have stereo option to allow stereo modulation: LFO, ADSR, HFO, Decay, Shaper, Clock, EnvFollow and S&H.
  • Stereo Modulation: Parameter knob's that are stereo-capable now have a "Stereo" option added to right-click-menu for individual channel control.
  • Stereo Modulation: Modules that have stereo knobs: All filters, Delay, Distortion, Phaser, Folder, Boost, Maximizer and Amplifier.
  • Added "Punch" to Amplifier module, to exaggerate or diminish positive amplification of Bipolar envelope modulation.
  • Added "Power Gain" option to Amp knob in Amplifier module, resulting in a non-linear gain curve, where a setting of 0.5 yields -3dB as opposed to -6dB.
  • Added "Clock" modulator module that outputs a steady and (optionally) free-running, digital, saw or pulse signal based on DAWs PPQ time.
  • Added "Boost" effect module that emulates the "Analog Boost" effect found in the Access Virus synth.
  • Modulation-phase-offsets are now treated separate from audio-phase-offsets. Added "Enable Phase Offset" knob-option to LFO Phase etc.
  • Selecting a Pattern/Step module's preset, now doesn't change the number of Steps of the currently active pattern.
  • Added Expression option to all "Mod" knobs, so modulation/envelope amount can be velocity/timbre controlled.
  • Added Pattern parameter to Step module with 8 available pattern slots + added "Copy" and "Paste" buttons to GUI.
  • Scope module now has sync to "Clock" option, which syncs scope to DAWs incoming PPQ time.
  • Added a "12 Octaves" range option to Freq knob for all Generators.
  • Added "Unity Gain" option to Shaper module, so lookup is passed-through instead of being halved and later multiplied by 2.
  • Added "Mod Link" option to Cutoff knob in all filters, that links Mod value to Cutoff with a 0% (default) to 100% setting.
  • Added Allpass filter to Parametric-filter module.
  • Default parameter modulation mode is now "Linear" instead of "Range-Scaled".
  • Added amplification Range option to Out parameter in ADSR module: 1 or 2. Default range is 2 (unchanged).
  • CPU: Expression now has a fast-code-path optimization, when no MIDI expression is processed.
  • GUI: Pattern/Step module's preset-menu now shows a checkmark next to the currently selected preset.
  • GUI: Shaper module's display can now be expanded to ease editing.
  • GUI: Added "Save Sample..." option to Sampler/Granular module's right-click menu, that saves selected sample as .wav file.
  • GUI: Moved Sampler/Granular module's "Crossfade Sustain" option into right-click-menu for sample editing. Now simply named "Crossfade".
  • GUI: Reworked Shift double-click in Sampler/Granular, so clicking inside sustain markers marks sustain area and otherwise entire sample is marked.
  • GUI: Added random history: Holding Shift while clicking Random or Shuffle in Pattern/Step modules will now undo last random/shuffle.
  • GUI: Added Pattern Semitone +1/-1 items to right-click-menu in Pattern module.
  • GUI: Reworked Envelope module's default-preset to have a standard ADSR style envelope and have Sustain enabled by default.
  • GUI: Pattern module's note-pattern can now be exported to MIDI (.mid), by right clicking and choosing "Export MIDI...".
  • GUI: Drop-Shadows in GUI are now animated when moving modules.
  • GUI: To reset EQ bars to default in EQ31, now simply use right mouse button.
  • Mac/OSX: Added Apple Silicon support on Mac/OSX 64 bit: arm64 M1/M2/M3.
  • Mac/OSX: Upgraded to latest Audio Unit SDK 1.2.0 on Mac/OSX 64 bit.
  • Mac/OSX: Removed libz dependency on Mac/OSX 64 bit.

  • Win32/64: Reworked Windows installer to allow for installation of KarmaFX Synth Core, VST2 and VST3 into 3 different folders.
  • Win32/64: PC/Windows Installer now remembers previous installation paths.
  • Bugfix: Feedback knob in FM module would not work in polyphonic mode, except for voice 0. Fixed. (Thanks Richard!)
  • Bugfix: Potential crash issue when receiving MIDI events while closing GUI. Fixed.
  • Bugfix: Modulating "Width" in Chorus module could cause overflow, due to read out-of-bounds. Fixed.
  • Bugfix: MIDI was not correctly processed in FM module, if any knobs in the advanced section were modulated. Fixed.
  • Bugfix: Loading .wav files with datasize larger than a multiple of their blocksize (faulty blockalign) could trash bytes in memory. Fixed.
  • Bugfix: Modulating resonance in SKF filter could result in high resonance near 0 due to missing clamp to 0. Fixed.
  • Bugfix: Very low rate interpolation could cause certain parameters to not update, e.g. in Formant filter. Issue introduced in v2.01. Fixed.
  • Bugfix: (fine)Tune knob in NotePitch module was incorrectly divided by 12 semitones. Issue introduced in v2.01. Fixed.
